Section 1. VEHICLE/TRAILER LOCATION
4.1 DRIVING THE LAUNCH VEHICLE AND PLS TRUCKS WITH OR
WITHOUT TRAILERS
ATTACHED
Speed Limits
4.1.1.1
The maximum speed of each M1977 CBT and M1075 PLS based launch vehicle, with
or without trailers, should be limited to 40 mph when operated on improved roads. If
traversal of cross-country terrain is necessary to access an operation site then the
M1977 CBT and M1075 PLS based launch vehicle, with or without trailers, should be
limited to a maximum speed of 15 mph. The M1076 trailers should be limited to a
maximum speed of 10 mph on Belgian block, cobblestone, or surfaces with heavy
washboard, ruts, or potholes.
Operating on Sloping Ground
4.1.2.1
Caution must be exercised when operating the DSB vehicles and trailers on slopes.
The DSB vehicles should be limited to side slopes not to exceed 20%. The possibility
of rollover exists on any slope (including level), but will be minimized provided that
operating speeds are kept to a minimum, no sudden steering inputs are made, and
depressions are avoided when traversing undulating terrain. Operators must be made
aware of these operating characteristics and limitations.
